AI Article Synopsis
- Parainfectious optic neuritis is caused by infections that either directly affect the optic nerve or lead to immune responses resulting in inflammation.
- A 13-year-old boy experienced severe vision loss in both eyes after a recent fever, with exams showing swollen optic discs and elevated inflammatory markers.
- After being diagnosed with parainfectious optic neuritis, he received corticosteroid treatment, which successfully restored his vision to normal levels.
Article Abstract
Parainfectious optic neuritis arises from infectious aetiology either from pathogen direct invasion or after an infectious disease which can be immunologically mediated demyelination of optic nerve or, from inflammation of optic disc vasculature. We report a case of bilateral optic neuritis in a young patient. A 13-year-old boy presented with painless profound vision loss in both eyes preceded by an episode of fever two weeks prior. Visual acuity in both eyes was a perception of light. Fundoscopy showed a bilateral hyperemic swollen disc. Blood investigations were normal except for C-reactive protein and ESR was elevated. CSF analysis was also normal with no growth of micro-organisms. Both CT scans and MRIs of the brain and orbit showed normal findings. The patient was diagnosed to have parainfectious optic neuritis. He was started on intravenous methylprednisolone for five days followed by a tapering dose of oral prednisolone for a total of one month. His final visual acuity improved to 6/6 in both eyes with a normal optic disc appearance.

Background: Hereditary Sensory Motor Neuropathy (HSMN) 1A and Multiple Sclerosis (MS) are distinct demyelinating disorders affecting the peripheral and central nervous systems, respectively. We present a case of simultaneous occurrence of both conditions, exploring the clinical presentation, diagnostic workup, and potential interplay between these diseases. Case presentation and clinical approach: A 49-year-old male with a history of optic neuritis presented with progressive numbness, weakness, and sensory loss in all extremities over four years.

Background: The new optic neuritis (ON) classification leads to a change in how ON patients are grouped. Our aim is to appraise the clinical features and prognoses of patients with autoimmune ON not associated with MS.
Methods: Patients referred to our neuro-ophthalmology laboratory were enrolled to this retrospective study.

Background: Neuromyelitis Optica Spectrum Disorders (NMOSD) comprise a group of autoimmune-mediated, inflammatory, demyelinating central nervous system diseases caused by aquaporin-4 (AQP4) IgG autoantibodies. Efgartigimod is a human IgG Fc fragment that reduces antibody titers by targeting the neonatal Fc receptor (FcRn). This study documents the efficacy of efgartigimod combined with intravenous methylprednisolone (IVMP) in the acute phase of NMOSD.

Objective: To define the epidemiology and clinical presentation of seropositive neuromyelitis optica spectrum disorder (NMOSD) in a large US health system.
Methods: We completed a retrospective observational study of adult patients in the University of Colorado Health System from 1 January 2011 to 31 December 2020, using Health Data Compass (HDC), a data warehouse that combines electronic health information with claims and public health data in Colorado. We screened HDC for patients with either (1) an abnormal aquaporin-4 IgG test or (2) any G36 ICD-10 code.

Objective: In this multicentric study, we were interested in the vision-related quality of life and its association with visual impairment in neuromyelitis optica spectrum disorders (NMOSD) and myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) in comparison to multiple sclerosis (MS) and healthy controls.
Methods: We analysed extracted data from the German NEMOS registry including National Eye Institute Visual Function Questionnaire (NEI-VFQ) scores, high and low contrast visual acuity (HCVA, LCVA), visually evoked potentials (VEP) and the scores for the expanded disability status scale (EDSS) and other neurological tests which assessed their disease-related impairment. The mean follow-up time of our patients was 1.
